Transmission Controls With PCM

TEST DESCRIPTION

Information flag 47 is set when the PCM fails internally.

NOTE: Record all PCM diagnostic trouble codes/information flags and include with repair information.

If this information flag is present and the only customer complaint is driveability, replace PCM.

Check the tightness of the female terminal grip with a spare male terminal.

When the PCM detects a fault in the circuit (open, ground, short) the PCM will open the circuit internally to protect the circuit.
